REINFORCING METHOD OF CAISSON SIDE WALL REINFORCEMENT AND REINFORCING DEVICE

摘要

PURPOSE: To save man-power of work by binding vertical reinforcing bars in a gap between an external frame and an internal frame of a positioning frame by making the side of the frame as a standard, and repeating a procedure to place horizontal reinforcement and haunch reinforcement while raising the positioning frame. ;CONSTITUTION: A positioning frame is constituted of an external frame 1, an internal frame 2 and an internal. frame holding plate 3, and the external frame 1 is combined with the internal frame 2 through the holding plate 3. After that, a gap is provided to a position to reinforce the side wall of a caisson, a part of the gap is also largely cut in the holding plate 3, and reinforcing bars held by reinforced arms 11 are arranged by making the positioning frame as a standard to position accurately. Then, vertical reinforcing bars 13 by making the side of the positioning frame as a standard are mounted to a gap between the external frame 1 and the internal frame 2 so that they are extended to the upper parts of the vertical reinforcing bars 13 after placing the reinforcement, haunch reinforcements 15 are placed to horizontal reinforcing bars 14, and reinforcing bars of the side wall are placed. When the bar arrangement of a cutting part of the holding plate 3 is completed, a hydraulic jack 23 on the base 22 is raised, a spacer 24 is inserted into a gap to raise subsequently the positioning frame, and a procedure placing the reinforcement is repeated.;COPYRIGHT: (C)1993,JPO&Japio
